Specification of Letters Patent. I Patented Apr. 13, 1920.

Application filed February 28, 1919. Serial No. 279,797.

To all whom it may concernk .Be it known that I, CHARLES J. HEN- scHEL, a citizen of the United States, re-.

siding at Brooklyn, county of Kings, and

State of New York, have invented certain new and useful Improvements in Electrically-Operated Vibratory Motors, of which the following is a full, clear, and concise descri tion 7 'lV y invention relates to electrically operated motors of the type used in electric bells,

interrupters, massaging machines and the like, and in which an armature, mounted upon a pivot or shaft, is caused to vibrate by the attraction and release of an electromagnet.

More particularly stated, I seek to produce an electrically operated vibratory m0-' tor especially-adapted for actuating a clapper used for striking a gong or the like, practically all of the mechanism of the motor, aside from the clapper and parts immediately associated therewith, being mounted upon a supporting frame, and this frame as a unit being removable bodily with its contents, without disturbing the clapper or the p v Reference is made to the accompanying drawing forming a part of this specification, and in which like letters indicate like parts throughout the several figures.

Figure 1 is a side elevation showing the motor mechanism as carried by the frame, this frame being detachably mounted upon a casing plate.

Fig. 2 is an end elevation of the mechanism shown in Fig. 1.

Fig. 3 is a plan view of the same.

Fig. i is a perspective of the removable frame used for carrying the various working 7 parts, and in this instance consisting of a single member of sheet metal.

Fig. 5 is a perspective of the armature forming a part of the motor mechanism.

8 is a perspective of a coupling key for faclhtating rapidity in connecting connecting the same therefrom.

casing plateis shown at 7. This plate may be either the top plate or bottom plate of a casing for holding the working parts of the motor. Y

The casing plate 7 is provided with thickened portions 8, 9, 10, serving the purpose of screw holders.

A. frame is shown at 11, and in this inwith screws 21, 22 are mounted thereof, as shown more ably fiber.

= motor mechani m with the ciapper and stance is made of a single integral member of sheet metal. The frame is provided with ears '12, 13, 14, adaptedto fit neatly upon thethickened portions 8, 9, 10. The cars are provided with holes 15, through which screws 16 may be extended into engagement with the thickened portions 8, 9, 10, so as to hold the frame detachaloly upon the easing member 7 The frame 11 is provided with a slanting portion 17, and fitted neatly upon the same is a block 18 of insulating material.

A pair of binding posts 19, 20, provided upon the block 18. Each of these binding posts is substantialy L-shaped, and extends crosswise of the :block 18 so as to overhang the edge particularly in Figs. 1 and p The block 18 is providecLwith screw holes 23, and is held in position by screws 24 which occupy these holes and extend into engagement with the slanting portion 17 of the frame 11.

Connected with the binding .posts 19, 20 are wires 25, 26. The wire 26 leads to a magnet 27, and the wire 25 leads to a metallic plate 28. t v

Engaging this plate is a contact spring 29, the form of which may be understood from Fig. 3. This contact spring is provided with an elongated straight portion 29, a shorter portion 29 bent to an angle to the portion 29, anda still shorter portion 29 bent into a tion 29*.

Associated with the magnet 27 is an arma ture 30, the general form of which is indicated in Fig; 5.

cated in Fig. 3. The pm 31 is double ended, and is made of insulating material, prefer It is used for striking the pertions 29 29 of the contact spring, as armature vibrates.

The armature 80 is mounted upon a pin 33, and is provided with a leaf spring 30 which, by pressing constantly against the adjacent portion of the magnet 27, serves to i retract the armature each time the magnet is deenergized. The pin 33 18 supported by a pair of ears 3e, integral with the frame 11 and havin the form indicated in F1 c5 13 The armature 30 is provided with slot 35, extending a slight distance into one its edges, as indicated more particularly in position parallel to. the por- The armature carries a buffer pin 31 extending through it as ind I ig. 5. -This slot is for the purpose of receiving a pair of lugs 36, carried by a rocking disk 37 and serving as a coupling key.

he rocking disk-37 is mounted upon a rocker shaft 38, which extends through a stufiing box 38 carried by the casing plate 7. The purpose of the stufling box is to render waterproof the group ofmechanism carried by the frame 11, while leaving the opposite or outer face of the casing plate 7' exposed to the weather. This is particularlydesirable when the device is used. at

sea.

-- Mounted fixedly upon the shaft 38 is a collar 39, which carries a cla per stem 40. This stem carries a clapper or striking a bell, these two last mentioned parts not behold the same in proper relation upon the ing all of the electrical mechanism and pr'ac- 'tically all mechanical parts except the clap- 5 and 6, the armature-30 is not secured to t frame 11. The magnet is provided with the usual insulated wire connection 48, for connecting together the spools of the magnet.

The operation of my v The parts being constructed and arranged as shown and as above described, the gen; eral operation of the electrical mechanism while in use is the same as in other mechanism of similar construction and action, as heretofore used in this art. Suppose, now, that the operator wishes to' disconnect the electric motor mechanism from the casing plate, say for purposes of inslpectlon or repair.

e simply removes the three screws 16, whereupon the sheet metal frame 11, carryper stem, is thus disconnected entirely from the casing plate 7 and all parts supported thereby.

As may be readilyunderstood from Figs.

I rocking disk 37 in any sense, the lugs 36 or coupling key fittingl loosely into the slot 35.

Hence, whenever e frame 11 is lifted off the casing plate 7 the armature 30 easily leaves the key, so that the stem 38 is not dis-' turbed.

To replace the electric mechanism, the frame 11 carrying it is put back in osition, care being used to see that the coup ing key extends into the slot 35, and the three screws 16 are then replaced.

Thus the problem of removing and renism shown, as variationstherein ma made without departing from the spirlt of without the necessity for disarranging. any

of the parts carried by the sheet metal frame.

I do not limit myself to the precise mechtamy invention.
